Works like a charm

Great plugin – have a premium version on one website, am using a free version on another. Both very good. Especially the premium version (obviously :)) – checks your performance, identifies problems and bottlenecks, and then helps you to minify/inline css and java (separately), as well as send things to the footer etc. For a non-coder such as myself, it’s hugely helpful. And the support team are the best I’ve come across.
Yay Hummingbird! Yay WPMUDEV!
